As he praised a recent Supreme Court ruling on same-sex marriage, Vice President Joe Biden on Thursday said more still needs to be done to protect LGBT Americans.

Biden spoke at an event in Manhattan hosted by Freedom to Marry, a New York-based organization. He praised the Supreme Court's recent ruling that same-sex couples have a right to marry anywhere in the United States, and said federal officials will continue to fight for the rights of the lesbian, gay, bisexual and transgender community.

Biden said he has been thanked across the country for his work on LGBT issues, but told the assembled audience Thursday, "You don't owe me or Valerie (Jarrett) or the president any thanks. We owe you."

White House adviser Jarrett also attended the function.

Gay Marriage Ruling Cheered Nationwide

"I really do think it is an incredible job you all have done," Biden told the crowd. "This has been a heroic battle."

He said members of the lesbian, gay, bisexual and transgender community had their "love constrained by social stigma and discriminatory laws."

"In my view, the court's decision was inevitable," he said. "So many remained silent for fear of being ostracized. You set them free."

He told several hundred other elected officials, community leaders, advocates and celebrities that more needs to be done to inform Americans that LGBT people can be fired from their jobs in 32 states because of their sexual orientation.

"There are still 32 states where marriage is recognized in the morning and you can be fired in the afternoon," he said. "I don't believe people in those states know you can be fired for being gay."

He said he believes people in those states would protest if they realized that is the law.
